I've got my iMac at home, which is my primary computer in terms of syncing. I also have my MacBook Pro that I use mostly at work. I keep the same mail/calendar/contacts setup on both Macs, but not the same music or photo libraries. I'd like to buy a dock for my iPhone to use at work, and be able to sync all my calendar/contact data while I'm there...and still be able to come home and sync up as well (calendar/contacts plus music and photos). Is this possible without screwing up the syncing with the iMac?
